Wiring an amp

I am sure you guys get tired of answering qustions like this, but I have to ask anyway.

I am hoping to wire in my amp on Sunday.  I starting laying cable, but when it came time to connect them to the amp itself, I ran into some confusion.  I feel like an idiot for asking, but I don't want to connect it wrong.

These are the connections on the amp.  It's a Rockford Fosgate Punch 201s 600 watt amp (will be running a 10" Rockford Fosgate Punch HE sub).

HP-AP-LP CROSSOVER (selector switch)

+12db/+6 db/0db (selector switch)

High Level Input (4 wire plug)

Left and Right POS and NEG connections 

B+

GND

This amp was running two of these subs before, but I only have room for one in it's new location.  I bought all of it used, so no documentation.

I undertand where the ground cable goes, and it appers that the B+ might be where my 12V source goes?  What about the signal wire?  I haven't done much of this...

Also, are the L and R + and - connections possibly for addition speakers?  Are they imputs?

Here is the manual for the 150S thru the 700S series of am[ps. Your amp is at max a 200W amp bridged int 4 ohms and thats at 14.4 Volts. Youcan look here also Crutchfield carries it and has info http://www.crutchfield.com/S-TRI5o7nytp3/cgi-bin/ProdView.asp?g=120&id=detailed_info&i=575201S#Inputs%20and%20Outputs The manual tells all. Hope it helps.

You are correct the B+ is power the GND is ground.

You wont use the High level imput (molex).

The left, right inputs hook to the RCA outputs from the back of your deck.

The REM input is where you put the wire coming from the remote turn on lead from the back of your head unit (must be connected).

The left right screw teminals that say bridged under them is where you connect you speaker leads. Connect them bridged to get full output from you amp.

So put your postive speaker lead on the 1st one from the left and your Neg speaker lead on the 4th one from the left.
